Specification of Letters Patent.

Patented NOV. 30, 1909.

Application filed March 24, 1909. Serial N 0. 485,386.

To all whom it may concern:

Be it known that I, JOSEPH F.. BETZLER, a citizen of the United States,and resident of Akron, in the county of Summit and State of Ohio, haveinvented certain new and useful Improvements in Composite Iens, of whichI hereby declare the following to be a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

The objects of the invention are to provide a composite pen having anincreased ratio of flexibility and resiliency over an all metal pen, andalso possessed of unusual efficiency and capability of retaining thesequalities for a long time without.change and of retaining its shapepermanently.

The pen is designed for use as an individual pen or with a fountainattachment for use with fountain pens.

The pen is composed preferably of vulcanite which is an extremelyelastic and flexible substance and the points are composed of platinum,iridium, or other hard metals capable of sustaining a hard durablesurface, and the points are integral with or attached to a wire loop orwires which encircle the slit in the pen. This loop is embedded in andvulcanized in the pen and hence prevents the points from becomingdestroyed and retains the pen in shape and the points in their properrelative positions. The Wire loop reinforces and adds to the stabilityand resistance to pressure in the body of the pen, and combined with thevulcanite body provides the exact degree of elasticity required. Theloop is formed of a wire which has its vertical sides deeper than thehorizontal edges thus adding to its strength and stiffness.

The invention is illustrated in the accompanying drawings, hereinaftermore fully described and the novel features thereof pointed out in theclaims.

In the accompanying drawings, Figure l, is a plan View of the pen, Fig.2, is a longitudinal section thereof, Fig. 3, is a perspective view ofthe integral wire loop employed, and Fig. 4 is a similar view showingthe metal wire pointed with some harder and more durable metal.

In these views 1 is the vulcanite pen, 2 is the wire embedded andvulcanized therein, 3 is the central slit about which the wire issecured. The points 4, I, may project if desired.

The wire is preferably similar in cross section to the one shown in Fig.2, but the exact shape can be varied to suit special conditions withoutdeparting from the spirit of the invention.

It is preferable that the vertical sides of the wire should be thewidest, thus adding greatly to the stiffness thereof.

I do not claim a metal pointed pen or nib inserted within a vulcanitebody, but

What I claim as new and desire to secure by Letters Patent is 1. Incombination in a pen, an elastic vulcanized body portion, and a loop offlat metallic wire having a ratio of less elasticity than said bodyportion, said Wire having greater thickness than width in cross sectionsand lying on its edge, the extremities of said Wire being broughttogether to form the points of said pen, and said loop embedded in andvulcanized in said elastic body portion.

2. In combination in a pen, a vulcanite body portion having alongitudinal slit, and a loop of fiat wire embedded in said vulcanitebody and vulcanized on edge therein, and encircling said slit, theextremities of said loop brought together at the outer extremity of saidslit.

3. In combination in a composite pen, a vulcanite body portion and aflat looped wire vulcanized therein on edge, said wire having a ratio ofless elasticity than said body portion, the extremities of said wirebeing brought together and projecting beyond said body portion andhardened points for the ends of said loops of wire.

4:. A pen body composed of a material having a high ratio of elasticityand provided with a longitudinal slit, in combination with a fiat metalwire loop having a less ratio of elasticity and vulcanized into saidVulcanized body portion, the said Wire encircling said slit on its edgeand projecting at its ends which are closely approximated together andadapted to form nib points.

5. In a pen, a slitted body portion of vulcanite and a fiat Wire memberembedded on edge in said body on each side of said slit, said Wiremembers being pointed and extending beyond the point of said vulcanite10 body.

I11 testimony whereof, I hereunto setmy hand this 27th day of February,1909.

JOSEPH F; BETZLER.
